An interesting logic puzzle

I thought this is a real cool problem… IT is all about logical thinking…

A teacher took out 8 stamps from a box – four of them white and four of them black. He got three of his brightest students – X, Y and Z and made them stand facing each other. He showed them the stamps, blindfolded each of them and then put two stamps on each of their foreheads. He put the final two stamps back in the box and closed the box. Then he opened the blindfolds. So, each of X, Y and Z could see the stamps on the forehead of the other two (but not their own – or the ones in the box). But they could obviously hear each other.

The teacher asked X first what were the color of the stamps (White White or Black Black or White Black) on his forehead. He said he did not know. The teacher asked then Y the same question. Y said he did not know either. Similarly the teacher asked Z and he too replied he did not know.

The teacher went back to X and asked if he now knew what he had. X again replied in the negative. The teacher asked Y next. And he did answer.

What was his answer? How did he deduce it?

Speed runs

After the hill runs, tried to push the leg muscles to take some pounding of speed runs. After a couple of miles of warm up, posted three 100 m dashes at 17 seconds, 16 seconds and 16 seconds each. That is about the time most pro runners would take if they also took a bio break in the middle of the dash 🙂 But for me that was a tough feat.

Then joined the Chalupa crowd for a quick 5K run in 25 minutes.

As always, it is great to see all the Chalupa folks – and especially the kids come out on a Sunday morning for some healthy exercises instead of sleeping in. The kids had a lot of fun after the run in their make shift camp at the back of a car 🙂

He did a Rajib on me!!

I have been preparing for a few days for my next trip to India to see my dad. Since this time I have a detour to another city (some work related stuff), I have been making a list of people I know in that city to see if I can create some more intersection points. It was in that context, I called up Aniruddha Sen in India. My classmate from early school days. In fact, we were in the same classroom in ninth grade (section B). I have not seen him in over 32 years, although I have talked to him – mostly on his birthdays.

I called him up hoping to see him for a few minutes while I would be in his city. The phone just was dead on the other end. Fearful that he has changed his number, I shot him an email and just let him know that I will be in his city for a few hours and should all stars align, it would be great if I could see him for a few minutes.

An email came back the next day essentially letting me know that the reason I could not get thru was that he was in flight. Flying to my city Atlanta!! He would be here for a few hours, he let me know – although busy till 9:30PM for work. 32 years versus staying up late – it was not even a question in my mind.

At 9:30 PM on this Tuesday, I finally met – after many many years – the guy with whom I sat in the same room six hours a day for days together!!! Getting to see Aniruddha Sen was a reward unto itself. Getting to know how well he and his family was doing was simply unbelievable!!
